ABSTRACT:
A system utilizing distributed on-chip termination. The system comprises a bus having a signal line and a first bus agent which is coupled to the bus. The first bus agent has a first termination circuit which is coupled to selectably terminate the signal line to a termination voltage. The system may further comprise an additional bus agent. The additional bus agent has a second termination circuit coupled to selectably terminate the signal line to the termination voltage. The bus in the system has a bus impedance, and the impedance of the termination circuit(s) is typically greater than twice the bus impedance.
